   private int speed;

   

   public Car(){

       yearModel = 2000;

       make = "Nissan";

       speed = 4;

   }

   

   public Car(int yearModel, String make, int speed) {

       this.yearModel = yearModel;

       this.make = make;

       this.speed =speed;

   }

   

   public void setYearModel(int yearModel){

       this.yearModel = yearModel;

   }

   public void setMake(String make){

       this.make = make;

   }

   public void setSpeed(int speed){

       this.speed = speed;

   }

   

   public int getYearModel(){ return yearModel; }

   public String getMake(){ return make; }

   public int getSpeed(){ return speed; }

   

   public String toString(){

       return "Car's year model: " + getYearModel() + ", make: " + getMake() + ", speed: " + getSpeed();

   }

}

<em>Variables</em> are declared.

<em>No-arg constructor</em> is created with default values.

<em>A constructor with parameters</em> is created.

The required <em>set methods</em> and <em>get methods</em> are created.

<em>toString</em> method is created to return car's specifications.
